Title: Improvements in and relating to stabilising ethylene oxide polymers or copolymers
IPC: C08K5/134
Filed: 1957-06-19
Abstract: Alkylene oxide polymers obtained by polymerization of ethylene oxide alone or mixtures of ethylene oxide with one or more other alkylene oxides, one of which may be unsaturated, are stabilized by addition of propyl gallate.  Other alkylene oxides specified are propylene oxide, styrene oxide, 1, 2-epoxybutane, 2, 3-epoxybutane and isobutylene oxide; butadiene monoxide, glycidyl crotonate, beta-methyl glycidyl crotonate, allyl glycidyl ether, allyl beta methyl glycidyl ether, divinyl benzene monoxide, 2, 5-dimethyl-5, 6-epoxy-1-hexene, allyl glycidyl sulphone, chloroprene oxide.  The mixture should contain at least 50% ethylene oxide, 0,3-0,6 parts of propyl gallate per 100 parts by weight of the polymer are used and discolouration of the stabilized mixture in the presence of iron salts may be prevented by addition of ethylene diamine tetracetic acid.  The stabilizer may be added to the polymer immediately it is formed or by making a dispersion of the polymer in a non-solvent, e.g. ethers, alcohols, esters, ketones or dioxane adding the propyl gallate and then evaporating off the diluent; mixing the stabilizer with the molten resin; dissolving the stabilizer in solutions of the resin in solvents, e.g. dimethyl formamide, acetonitrile, methanol, acetic acid and mixture of benzene and water.  Tables are given of the per cent loss in viscosity when the polymer has been aged for twenty minutes (a) in absence of a stabilizer; (b) in presence of a number of known phenolic, amine and naphthylamine stabilizers; (c) in presence of propyl gallate.  Suitable co-polymers to be stabilized are as claimed in Specification 869,112. Specifications 818,737, 869,115 and 869,116 also are referred to.

Abstract: 655,942. Electric pick-ups. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. July 18, 1947, No. 19269. Convention date, July 22, 1946. [Class 40 (iv)] An electric pick-up for indicating or recording the instantaneous displacement, velocity or acceleration of vibrating parts comprises an electromechanical transducer and a feedback mechanico - electrical transducer to reduce errors caused by conditions such as fre-. quency or temperature. A crystal 21, Fig. 3, feeds an amplifying valve 30, part of the output of which energizes a moving coil 27 rigidly connected to a rod 22 connected to the crystal, the force exerted by the coil enhancing the effect of the elasticity of the crystal, whereby compensation is made for temperature. In Fig. 4, the output of a moving coil 41 is fed to an amplifying valve 45, the anode circuit of which feeds a second moving coil 42 to damp the velocity of displacement of the first coil, the output across the resistance 47 being proportional to the acceleration of the system relative to the housing. The feed-back increases the range of frequencies at which the device will operate satisfactorily.

Title: Improvements in or relating to gaseous discharge tube counting chains
Inventor: BRANCH MAURICE CHARLES
IPC: G11C19/20
Filed: 1952-08-11
Abstract: 702,256. Multi-stable state discharge tube circuits. STANDARD TELEPHONES & CABLES, Ltd. Aug. 11, 1952, No. 20148/52. Addition to 677,872. Class 40 (6) A counting chain of gas-filled discharge tubes comprises a coincidence gate circuit between each pair of consecutive tubes in the chain each gate interconnecting the anode of the first tube of a pair, the trigger electrode of the second tube and the common lead to which triggering pulses are applied so that the second tube fires only when the discharge of the first tube and a triggering pulse on the common lead occur simultaneously. Fig. 1 shows a section of a counting chain comprising cold-cathode gas-filled discharge tubes T1-T3 in which positive-going triggering pulses are applied simultaneously to all the stages from terminal P. If tube TI is initially discharging then its anode potential is low so that when a positive pulse appears at P rectifier MR1 conducts and a positive pulse is applied to trigger tube T2. When the tube T2 fires tube T1 is extinguished by the action of the commutating capacitor C2. The next trigger pulse at P advances the discharge from tube T2 to tube T3. Rectifier MR2 limits the maximum triggering pulse amplitude at P to some 130 volts and on each occasion when tube T3 fires rectifier MR5 conducts to pass the next triggering pulse from P to the output O. In a modification shown in Fig. 2, the firing of all of the tubes of the chain on switching on the H.T. supply is prevented by biasing the trigger electrode of each tube negatively via a resistor R6 and via an earthed rectifier MR6 so that normally the trigger electrode is maintained at or near earth potential. When the H.T. supply is switched on rectifier MR6 is biased to its high resistance state and spurious firing of the tube is prevented. In a further modification shown in Fig. 3 positive triggering pulses are applied at PB and negative triggering pulses at AP in synchronism. Information is inserted in the circuit by firing or not firing predetermined tubes of the chain by means not shown, and the pattern so stored is progressed one tube along the chain by each combination of a positive and negative pulse pair applied at AP and PB in synchronism. Specification 663,574 is referred to.
